For a radioative substance, write the relation between:
Half life (T) and disintegration constant `(lamda)`

For a radioative substance, write the relation between: Mean life (tau) and disintegration constant (lamda)

The relation between half - life period (T_(1//2)) and disintegration constant (lambda) is expressed as

The relation between half - life period (t_(1//2)) and disintegration constant (lambda) is expressed as

Obtain a relation between half life of a radioactive substance and decay constant (lamda) .

Using the equation N = N_(0)e^(-lambdat) , obtain the relation between half-life (T) and decay constant (lambda) of a radioactive substance.

Answer the following: (a) For a radioactive substance, show the variation of the total mass disintegrated as a function of time t graphically. (b) Initial mass of a radioactive substance is 3.2 mg . It has a half-life of 4 h . find the mass of the substance left undecayed after 8 h .

Give the relation between half life and initial concentration of a reactant in a zero order reaction

A certain radioactive substance has a half-life period of 30 days. What is the disintegration constant ?

1g of a radioactive substance disintegrates at the rate of 3.7xx10^(10) disintegrations per second. The atomic massof the substance is 226. Calculate its mean life.

Half-life of a radioactive substance is 20 minutes. Difference between points of time when it is 33 % disintegrated and 67 % disintegrated is approximate.
